Cut ¼ cup of the roasted peppers into thin strips; reserve for the garnish. Finely chop the remaining roasted peppers.
In a large bowl, combine the finely chopped roasted red peppers, bread crumbs, egg whites, tomato sauce, basil, ¼ cup snipped parsley, salt, and black pepper.
Add ground beef, mix well. Lightly pat the ground beef mixture into a 9x5x3-inch loaf pan.
Bake, uncovered, for 1¼ to 1½ hours or until an instant-read thermometer inserted in the center of the meatloaf registers 160°F.
Garnish with the reserved ¼ cup roasted red peppers and additional parsley. Slice into 6 even pieces to serve.
